laravel 的视图合成器可将数据与指定视图绑定在一起，避免了重复编写代码。
view::composer('profile', 'app\http\view\composers\profilecomposer');
由于数据的生成和渲染是分开进行的，理解起来不够直观。因此，可以采用视图组件的方式将两者进行封装。
<?phpnamespace app\viewcomponents;use illuminate\contracts\support\htmlable;use illuminate\http\request;use illuminate\support\facades\view;class examplecomponent implements htmlable{ private $color; private $request; public function __construct(request $request, string $color) { $this->color = $color; $this->request = $request; } public function tohtml() { return view::make('example') ->with('color', $this->color) ->render(); }}
在视图中使用
{{ app()->makewith(app\viewcomponents\examplecomponent::class,['color' => 'green'])->tohtml() }}
封装指令
blade::directive('render', function ($expression) { list($class, $params) = explode(',', $expression, 2); $class = "app\\viewcomponents\\".trim($class, '\'" '); return "<?php echo app()->makewith('$class', $params)->tohtml(); ?>";});
使用指令
@render('examplecomponent', ['color' => 'green'])
